Effect

Avalanche deals damage and is a decreased priority move, causing the user to attack after other Pokémon that are using ordinary priority moves. If the user takes damage in the same turn, Avalanche's power is doubled to 120.

Pokémon Mystery Dungeon

Similar to Bide, the user will store energy for a few turns and then release the energy to inflict damage, the amount of damage equaling the amount the user received during the "charging." The move will fail if the opposing Pokémon doesn't attack, if the user is under certain statuses like sleep or paralyze, or if the user faints.

Trivia

In the Spanish version of the Generation IV games, Avalanche was translated as "Alud". While this is not incorrect, "alud" refers more to a rock slide than an avalanche. This was done likely because of the move Rock Slide, which was translated as "Avalancha", much in the same way that Dawn's name was translated to reference May's English name.

If Secret Power is used on snow or ice in Generation IV, it will have the animation of Avalanche.

In the Chuang Yi translation of the Emerald arc of the Pokémon Adventures manga (into English), Factory Head Noland orders his Golem to use Avalanche on Emerald's Sceptile. This is likely to be a mistranslation, as Rock Slide was the actual move used, and Golem couldn't learn Avalanche through TMs.
